行前交通信息提供下路线选择行为的影响因素分析

Analysis of impacting factor of route choice behavior with pre-trip information

在行前交通信息提供下,驾驶员的路线决策行为在众多因素的作用下非常复杂。传统的研究方法缺乏对各影响因素的定量分析,模型中也鲜有考虑驾驶员的态度认知变数。为进一步探讨行前交通信息提供下驾驶员路线选择行为的影响因素,本研究提出3个基本假设,并采用结构方程模型对假设进行验证。结果显示:3个假设均成立,即路线选择行为与行前提供的行程时间成负相关,与路线的利用经验成正相关,与路线的认知评价成正相关。其中,出发前行程时间信息对通勤者的路线选择行为影响最大,路线的印象评价影响次之,最后是路线的利用经验。研究结果有助于正确把握驾驶员在交通信息影响下的决策行为。

The drivers' route choice behavior become very complicated with many impacting factors when pre-trip information is provided.The traditional studies lack quantitative analysis of the impacting factors with the information of drivers' attitude variable.To study the decision-making mechanism of drivers' route choice behavior,three basic assumptions of route choice behavior with pre-trip information were assumed,and tested by a structural equation model.Results showed that the assumptions were valid.The route choice behavior was negatively correlated with the provided pre-trip information,and was positively correlated with trip experience as well as the cognitive evaluation of the routes.The results helped to understand drivers' route choice behavior well when traffic information was provided.
